The outrageously funny BBC sitcom "Cuckoo" returns to BBC One this week for its fourth season after its move to BBC Three's digital online format for the season prior. Taylor Lautner returns as the loveably naive Dale while Greg Davies, Tyger Drew Honey, Helen Baxdale and Esther Smith reprise their roles as the members of the Thompson family. The season kicks off with Dale planning to ask for Ken's blessing to propose to Rachel but is told to get a job and a stable life before doing so. Elsewhere, Ken faces an uphill battle in pursuit of the Lichfield Lawyer of the Year award - that is, until Lorna starts hatching a plan to sabotage his opposition. Cuckoo - Monday 10:45pm on BBC1.
